Are you sure you want to do that? Envision allows you to keep a member's information while simply marking them as Inactive. This way, you always have contact information when you want to send mailers out to those you haven't seen in a while. Inactive members are perfect for inviting to special events or homecoming services, etc. But if you really want to get rid of a person's record, just move to their record and click the delete button.
NOTE: All attendance information for the person is deleted when you delete their record. This is another reason you may not want to delete a person's record.
